Packaging with 2to3
Hi, I want to create a package (pyraf, #711038) for both Python2 and Python3. While the package itself is still not Python 3 compatible, upstream says that running through 2to3 will make it; however the resulting code is not Python 2 compatible anymore. Is there a way to instruct pybuild to run the Python 3 code through 2to3? Best regards Ole

Sixer will patch the code in a way so that it works with both Python 2 and 3. Note that it wont do *all* for you, like you'll have to convert print statements into function calls manually, but it does a big chunk, which is quite helpful. I hope that helps, Cheers, Thomas Goirand (zigo)
